Walkinshaw Andretti United broke a 23-year title drought following a brilliant Finals campaign from Chaz Mostert.
Mostert won the opening three races of the Finals Series, and only finished off the podium once in the last four races to secure his first title.
Teammate Ryan Wood also starred in his second season, winning his first race in Perth and claiming three pole positions.
2026 marks a brand new chapter with not only the debut of Toyota, but also a change in the ownership structure of the team which will bring a name change from February.
United Autosports, the sportscar team led by McLaren CEO Zak Brown, will exit the ownership group after eight seasons with the team, which will be renamed Walkinshaw TWG Racing from February 3.
Andretti Global got absorbed into Dan Towriss' TWG Motorsports group over the Christmas period in 2024-25, with the group best known as the driving force behind General Motors' Formula One entry with Cadillac this year.
It's been a big six years in WAU colours for Mostert, who famously dominated the Great Race weekend in 2021, setting a lap record before winning the race with Lee Holdsworth.
Mostert won multiple races in 2021 and 2022, and after a winless 2023, returned to form in a big way in 2024, with a late season slump undoing a mid-year form surge.
What was the Holden Racing Team until the end of 2016 welcomed Andretti Autosport and United Autosports as partners in 2018.
After two years of solid yet unspectacular results, the WAU international alliance decided to throw everything at signing Mostert as their spearhead – and they got their man.
They wiped the slate completely clean, hiring reigning Dunlop Super2 Series champion Bryce Fullwood as Mostert’s teammate.
In 2020, Mostert finished fifth overall and claimed a Bathurst podium, while Fullwood impressed to earn himself a contract extension.
Mostert won in Tasmania and Darwin in 2021, before he arrived in Bathurst and blew his rivals away.
Founded by Tom Walkinshaw, the team enjoyed a rich history during more than two decades as HRT.
It won races, titles and Bathurst 1000s with the likes of Peter Brock, Craig Lowndes, Mark Skaife, Garth Tander, Jason Bright, Greg Murphy and Todd Kelly.
Its international partners played a role returning to the front; led by former racer Michael Andretti, Andretti Autosport has six Indy 500 wins and five IndyCar Series crowns to its name, and also runs Formula E and Indy Lights programs.
Andretti Global was placed under the umbrella of Dan Towriss' TWG Motorsports group in early 2025, with the group best known as the driving force behind General Motors' Formula One entry with Cadillac this year.
